Our maths grid
Posted by Miss W. on May 14, 2010
In maths, some students have been looking at addition grids. You have to find pairs of numbers that add up to 100. There will be one number not paired up. You, the reader, have to leave a comment telling me what the number is and also what you need to add to get to 100.
